Hi Renkai,

thanks for the interest in Flink and the Table API/SQL! I would 
recommend to maybe have a look into previous Pull Requests for new SQL 
features such as INTERSECT [1] to get an overview of layers and classes. 
I also recommend the design document [2] that describes the all planned 
features. It might be good if you look for an easy task to start with [3].

[1] https://github.com/apache/flink/pull/2159

Hope that helps.

limited currently. I want to help improving related features, such as distinct aggregates
for SQL on batch tables, and aggregations for SQL on stream tables. I don’t have much experience
in developing SQL related things, what could I do for these?
